The steam supplied by the power plant is at 2.0 MPa(g), and it is used by enterprises outside the plant; it is delivered through GB2 pipelines. What design, construction, and acceptance standards apply? The current standards for urban pipeline networks apply to steam pressures in the range of 0~1.6 MPa, except that CJJ104 applies to steam pressures in the range of 0~2.5 MPa.
Same question. The external supply pipeline of the power plant is 27 kilometers long, with a design pressure of 2 Mpa and a temperature of 310°C; the medium is superheated steam, and it is installed in both overhead and buried configurations. For direct burial, CJJT104 can be used as a reference; but what is the basis for overhead installation?
